Re: how to save in inline form total sum

Hi +Collin the idea is sum all data for example de model is

class ModelB(models.Model):

    choice = models.Integerfield(choices='CHOICE_TYPE')

    men = models.IntegerField()

    women = models.IntegerField()

    total_men = integerField(editable=False)

    total_women = integerField(editable=False)

    fk_model_a = fk(ModelA)

    def save(self, *args, **kwargs): #this is for sum all 3 data put in admin inlines

        self.total_men += self.men

        self.total_women += self.women

        super(ModelB, self).save(*args, **kwargs)

in the admin look liked this:

ModelB in inline

choice               men           women

option1               6                   4

option2               1                   3

option3               2                  1

i need save in other field total this sum for example men = 9  and women total is = 8

for this reason i create 2 field more 

 total_men = integerField(editable=False)

 total_women = integerField(editable=False)

and create the override save method

def save(self, *args, **kwargs): #this is for sum all 3 data put in admin inlines

        self.total_men += self.men

        self.total_women += self.women

        super(ModelB, self).save(*args, **kwargs)

but no working :(

any idea to save the sums of the inlines options

Cheers

Hello,

I'm not sure what you're trying to do, but to fix the None error set default=0 on the total columns.

Or do something like this:

self.total_men = (self.total_men or 0) + (self.men or 0)

Thanks,

Collin
